MACHINERY OR APPARATUS FOR CLEANING TIN AND TERNE PLATES.

SPECIFICATION forming part of Letters Patent N 0. 428,994, dated May 27,1890.

Application filed July 12, 1889. Serial No. 317,354.

To all whom it may concern:

Be it known that I, JAMES ABBOTT, a subject of the Queen of GreatBritain and Ireland, residing at Blaina, Kingdom of Great Britain andIreland, have invented new and useful Improvements in Machinery orApparatus for Cleaning Tin and Terne Plates, (for which English patents,No. 7 ,366, May 3, 1889, and No. 10,116, June 21, 1889, have beenobtained,) of which the following is a specification.

This invention relates to the operation of cleaning tin and terneplatesby dipping them in bran for the purpose, as is well understood, ofremoving grease remaining upon them after withdrawal from thegrease-pot.

This invention consists, first, in a method of and means formechanically cleansing both sides of the plates by passing them throughtwo troughs in succession, each trough containing bran and placed onebehind the other. The plates are mechanically passed through the fronttrough and transferred therefrom to the second or rear trough. They arereversed or turned over at the time of transfer.

In Figure 1 of the accompanying drawings is shown aplan of apair oftroughs a, arranged and fitted for cleaning tin and 'terne plates inaccordance with this invention. Fig. 2 is a vertical section. Figs. 3and 4c are similar views to Figs. 1 and 2, respectively,illustrating amodification.

Referring to Figs. 1 and 2, in each trough are three sets of forked arms0, each set being mounted at suitable distances apart on a shaft 1),carried in bearings at each side of the trough. At one end each shaftl)is fitted with a toothed wheel to, gearing with the pinion y, driven bythepulley Y, keyed on (No model.) Patenteclin England May 3, 1889,110.7,366, and June 21, 1889,N0.10,116-

the shaft 5. Each trough a contains bran, the upper surface of which isroughly indicated bythe dotted lines at, Fig. 2. Each plate p onentering in proper turn the front trough is received in a bend of theforks c, of which three are presented thereto abreast. By the forks theplate, which is kept raised by guides (Z, is lowered to the bottom ofthe trough, from which point it is forced upward through the bran to thedentated tilting table j, which normally lies in the position indicatedin dotted lines, Fig. 2, and is carried on most which was downward inthe first trough.

On arriving at the rear end of the second trough the plate approximatelyuniformly cleansed on each side is tilted by the dentated tilting tablef onto the shelf h. The rack by which the plates are fed to the firstcleaning-trough consists of a skeleton drum having radial arms 1'springing from a spindle j, carried in bearings, as shown. Upon theseradial arms are laid the plates 1) to be cleaned.

Those forked arms 0 which are situated toward one side of the fronttrough are furnished with strikers 7r, Fig. 1, which as the arms rotatestrike in turn against the bent arms Z fixed to one side of the rack,which latter is thus caused to rotate and to discharge into the troughthe plate lowest in the rack. The rack is prevented by the spring m,acting on the recessed pinion n,from-rotating at one time farther thanis required to deliver one plate into the trough.

Figs. 3 and at show a modification of this invention, under-which theplates for cleaning are seized between spring-jaws and drawn through thebran, instead of being thrust through it, as in the arrangement firstabove described. On the shafts h, driven by suitable gearing, are keyedthe arms 0, which retate in the troughs a. as the shafts I) revolve. Ateach extremity of each arm 0 is a jaw composed of a rigid member (Z anda member (1', capable of turning on the spindle '1', which connects allthe jaws in each separate parallel series. By springs c, fixed to thearms 0 and bearing against the hinged members of the jaws, the latterare normally kept closed. Pivoted in brackets g situated toward the rearof each trough, are levers 7, having fingers Z extendinginward-that isto say, transversely to the longitudinal axis of the troughs. The leversZ, which toward their tail have curved projections 7 lie normally in theposition indicated in dotted lines at Fig. 4:. At the front end of eachtrough, at each side thereof, is a curved bar 71 so situated relativelyto the center of the shaft 1) and the spindle t that the latter, whenbrought into contact with the bar 71, is thrust outward, and the springa, being thus depressed by the pivotedmembcr (Z of the jaw, the jaw isopened. Into it is inserted the plate 17, which is gripped by the jaw assoon as the spindle 1 passes clear of the bar h. Assuming now that aplate 1) has been inserted in the jaw at the front of the leading troughit (the plate) is drawn through the bran, the surface of which isroughly indicated by the dotted line a, Fi g. -l, as the arms 0 rotatewith the shaft 1). On reaching the rear end of the front trough thelevers Z thereat are tilted by the spindle i against the stops g, formed011 the brackets g. The arms continue to rotate, and when the spindle'21 is brought into contact with the raised part Z on the levers thesprings e are overcome, the jaw is opened, and the plate 1), directed bythe levers l and fingers Z, drop into the jaw on the arm (2, presentedfor its reception at the front of the rear trough.

\Vhen the spindle of the jaw from which the plate drops has passed theprojections Z on the levers l of the front trough, the said levers swingback to their normal vertical positio 1. The plate now delivered to therear trough is carried through the bran therein (indicated by the lineat, Fig. l) in the same manner as in the leading trough, but having thatface uppermost which in the first trough was downward. The plate isreleased and discharged onto the delivery-table 75 by similar means tothose by which it is transferred from the front to the rear trough.

\Vhat I claim is- 1. In a machine for cleaning tin and terne plates, thecombination, with two cleaningtroughs, each to contain bran or othercleaning substance, of sets of revolving arms, each adapted to receiveand pass a plate through one of said troughs, and a transferring devicelocated between said troughs and adapted to automatically cause a plateto pass from one set of arms in the first trough to another set of armsin the second trough, said device being operated by the firstmentionedarms, substantially as herein described, for the pur pose specified.
